The answer depends on: 1) how academically strong you are 2) how badly you wish to get accepted to TJ?, and 3) how much discipline you have to do it by yourself? The biggest challenge in doing it yourself will be in determining, how well-prepared you are at any given point in time? To answer this question you will need historical and current information as to where you stand vis a vis your competition. There is only one chance for admission to the TJHSST as a freshman, so if you are seriously interested in attending the Thomas Jefferson High School for Science and Technology (TJHST), you should explore all your options and then make a final decision.
